Microsoft founder(创建者) Bill Gates has talked about         to be a good parent, saying that 13 is a right age for a child's first mobile phone.
The 57-year-old father of three said on the Today show that his children Jennifer and Rory were not allowed to have their        phones until their 13th birthday and his youngest daughter Phoebe is still         for one.
“We've made a rule in our family that it's 13 when you get a phone.” He also said as a result his child often returned       from school complaining, “All the other kids have one, I'm the only student     it, it's so embarrassing(令人尴尬的).”
Bill Gates        said that they want to raise（抚养）their three children as usually as possible. It is said that their kids have to do        at home and can’t get much money.
In 2010 Mr. Gates said that he wanted to give most of his money       instead of handing it down, “That wouldn't be good either for my kids or society,” he said.
